I bought a steering wheel on eBay as a donor to have modified - not sure what this wire is, but it looks like it goes behind the leather for heating. Could be wrong and it's for something else but if so cool bonus!

Seems likely that it does. Wasn't there any item description saying it had heat?
Maybe they were looking for a dash button to base that on and of course if it was a 20 or 21 there was no button, and if they didn't start the truck they didn't see the screen either when in fact the truck did have it. ¯\_(ツ)_/¯ Speculation of course
